I can go on and on. I have been using wide LSA stuff since the late 90's with plenty of success. In street and race stuff. Our BB Camaro has a 114 and is a street car that runs 9's on pump gas at 3600+lbs with a tad over 9-1 compression. My Belvedere was 11.2-1 and had a 116 went mid 10's on pump gas at 3700lbs. My Valiant was on a 117, the Duster was a 114, with iron heads. As I say I can go on. All of the race motors had 13-1 or more compression of course. Its all about the combination not one magic part. For me wider has been better.

As for rod length. It don't matter, within reason. Get the stroke you want, the piston design you are happy with and order the rod accordingly.
